This digital dataset defines the surface traces of regional geologic structures designated as potential ground-water flow barriers in an approximately 45,000 square-kilometer...

These contours represent the simulated potentiometric surface at the end of simulation (1998) in model layer 16 of the Death Valley regional ground-water flow system (DVRFS), an...

This digital data set defines the hydraulic-head values in 16 model layers used to initiate the transient simulation of the Death Valley regional ground-water flow system...

This digital dataset defines the surface traces of regional features simulated as horizontal flow barriers in the Death Valley regional ground-water flow system (DVRFS)...

This digital data set represents discharge areas in the Death Valley regional ground-water flow system (DVRFS) transient model. Natural ground-water discharge occurs by way of...

The raster-based classification of evapotranspiration (ET) units is for nine major discharge areas in the Death Valley regional flow system. The ET units delineate general areas...

The raster-based, color-infrared composite was derived from Landsat Thematic Mapper imagery data acquired during June 1992 for the Death Valley regional flow system. The image...

This digital data set defines the boundaries of the deserts of the southwestern United States. Those deserts include the Great Basin, Mojave, Colorado, and Sonoran Deserts as...

This digital data set defines the lateral boundary and model domain of the area simulated by the transient ground-water flow model of the Death Valley regional ground-water flow...

A digital three-dimensional hydrogeologic framework model (HFM) represents the geometry and extent of hydrogeologic units (HGUs) and major structures in the Death Valley...

This digital geospatial data set is a compilation of reference points representing springs in Nevada that were used for the regional ground-water potential map by Bedinger and...

This digital data set defines the lateral boundary and model domain of the area simulated by the transient ground-water flow model of the Death Valley regional ground-water flow...

The digital data set provides point locations and general descriptions of areas photographed to document sites visited during a study to refine current estimates of ground-water...

This digital data set defines the boundary of the ground-water flow model by D'Agnese and others (1997). This steady-state, 3-layer ground-water flow model was developed by the...

Recharge in the Death Valley regional ground-water flow system (DVRFS) was estimated from net infiltration simulated by Hevesi and others (2003) using a deterministic mass-...
